A metabolism trial was conducted to determine the influence of corn kernel traits on digestibility. The seven hybrids used in this study were the same as those fed in a feedlot performance trial where kernel traits were correlated to feed efficiency. These hybrids were selected to represent a range within and among kernel traits. There were no differences in total tract digestibility for hybrids that have softer endosperm. Ruminal pH parameters and intake behavior were not found to be different for animals in the metabolism trial. However, differences did exist among hybrids for volatile fatty acid production. VFA production over time was similar for all treatments with a peak in total VFA concentrations five to seven hours after feeding.
